Integrated Laparoscopic Tool with Movable Grasping Assist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In laparoscopic surgery, existing systems require multiple tools and manual coordination by surgeons and assistants to perform dissections and grasping operations, especially for large organs, which can be cumbersome and inefficient, particularly when trying to maintain a clear operative field and apply traction.
Innovation Solution
A treatment tool system with a support portion, treatment portion, assisting portion, and control mechanism that allows for independent operation by a single surgeon, featuring a mode-switching capability to adjust the position and movement of the assisting portion relative to the treatment portion, enabling precise control and reduced need for multiple holes in the abdominal wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple treatment tools are used for dissection and grasping operations, then the ability to perform complex surgical tasks is improved, but the number of holes in the abdominal wall increases and manual coordination becomes cumbersome
Solution Approach 1:
The patent combines multiple treatment tools (grasping tool and dissection tool) into a single integrated treatment tool. The distal end of the insertion portion includes both a treatment portion for dissection and an assisting portion with grasping function, allowing both grasping and dissection operations to be performed through a single hole in the abdominal wall, thereby reducing the number of holes while maintaining the ability to perform complex surgical tasks
Solution Approach 2:
The treatment tool is designed with multi-functionality, where the insertion portion serves multiple purposes: it includes both the treatment portion for dissection operations and the assisting portion for grasping and traction. This universal design allows a single tool to replace multiple specialized tools, reducing the need for multiple holes in the abdominal wall
2Adaptability or versatility
If multiple treatment tools are used for dissection and grasping operations, then the ability to perform complex surgical tasks is improved, but manual coordination between surgeons and assistants becomes cumbersome
Solution Approach 1:
The patent combines multiple treatment tools (grasping tool and dissection tool) into a single integrated treatment tool. The distal end of the insertion portion includes both a treatment portion for dissection and an assisting portion with grasping function, allowing both grasping and dissection operations to be performed through a single hole in the abdominal wall, thereby reducing the number of holes while maintaining the ability to perform complex surgical tasks
Solution Approach 2:
The assisting portion is configured to automatically follow the movement of the treatment portion, eliminating the need for separate manual control. When the treatment portion moves, the assisting portion automatically adjusts its position and maintains grasping force, allowing the tool to serve itself and reducing the need for manual coordination between surgeons and assistants
3Device complexity
If the assisting portion is fixed near the treatment portion, then the structure is simple, but the ability to maintain clear operative field and apply traction is limited
Solution Approach 1:
The patent makes the assisting portion movable relative to the treatment portion along the longitudinal axis of the insertion portion. The assisting portion can be positioned at different distances from the treatment portion depending on surgical needs, allowing it to follow the treatment portion during insertion or be positioned separately to maintain a clear operative field and apply effective traction, thus introducing dynamic adaptability to the structure

AI summary
A treatment tool includes: a support portion which is formed in an axial shape; a treatment portion which is disposed at a distal end portion of the support portion; a treatment assisting portion which is disposed at the distal end portion of the support portion, which has an assisting portion, and in which the assisting portion is capable of being moved between a first position and a second position; a driving portion which moves the assisting portion of the treatment assisting portion; an operation detection portion which determines an amount of movement of the support portion, which is inserted into an introducing tool, with respect to the introducing tool, and an orientation of the support portion; an operating portion which is disposed at a proximal end portion of the support portion; and a control portion which controls the driving portion based on a detection result of the operation detection portion.
